BATTER-Y GRID AND ?BOCESS OF MAKING SAME.

3T0 Drawing.

To all whom. if may omwern:

Be it known that E. HIRAM L. EDNEY, ,a citizen of the United Stntesesidingut Wirt, in the countv of Carter nnd State of Oklahoma. have invented certain new and usefui Improvements in Battery Grids and Procasses of Making Same of which the follow ing. is a specification.

This invention relates to storage battery piates or grids and the process for making the same.

Oneobject of the present invention is to evolve a process whereby storage battery Iotes or ids ma be uicki n'oduced githout ug aisa reiiabie ieaturzas nnd liability to harm t e workmen attending the manufacture of such plates by processes heretofore employed.

A further object of the invention is to produce a battery flat-e or grid by a process which will provi e for Ehe protection against heat of the active material of the piate.

[Another object of the invention is to evolve a process whet-oi? such piates may he made Hoof against rea y disintegration and will possess the desired degree of porosity.

My inventio z'relates both to the menufacture of po%i ye and .negative plates and I will first (lee ilbe the'mannsr inwhich the positive plate is produced. I first mix one pint of suifurioacid of 1200" specific en-avity and one ounce of liquid ooiiodion and stir this mixture until a white scum appears on the surface. I next skim or otherwise remove this scum and add to the solution onehalf ounce of bicarbonate of'soda and one ounce of giyeeriue (U. S. P.). The result-V Eng mixture is then incorporated with a su fluent quantity of red lead to reduce :1 m5. or uimostdrypaste, and whi e the paste is still hot, heat being amended as a resuit of Chemical reaction w ich takes piece,- I fiii this paste into the iead grids. The plates tilus produced may then be passed between rubber nails or may be smoothed off with a, trowel or other implement and after being thus treated they are dried eiiher in a warm phice or referabiy in an oven.

After he piates have been drier iiiey are ready for the forming process and in carrying out this woe-ass I add to one quarto? hard water three ounces of bicarbonate o? Soda and one ounce of aluminum suifate T he plates or 'fiiied grids are then immersed in this soiution and are charged with for e:-

ample ten nmperes for seven piaies in a group, three positive and four negative.

I employ mllorlion for the reason that it W11] withstand enormous heat without deteriorating and therefore serves to protazt the active material and likewise {)IQa'flflfi' deterioration of the giyoerine empioyed. My reason for employing bicarbonate of soda is that the acid wiii react with this ingredientto generate cal-non diozzid gas which will give to thepiutes the desired porosity. i employ aluminum sulfate for the purpose of causing the active muieriai to draw together of shrink and thus bind the coilodion and g1 ycerine together, and this ingredient serves Ems purpose without destroying the porosity of the pletai. i

The negative plates are prepared in substantialiy ihe same manner as the msiiii'o plates, so far asmechonicai z-rteps of the process are concerned but in preparinw the filler for the negative plates 11 use about onequarter pin'mof suifuzic mid of 2150 sracific gravity mixed with two 01mm of Irish giuel- Haiing thus described the Em'erstion, What is'ciaimed us new is:

1 The process oi. battery positive piata which comprises; fill ieig e suitable gnd viii: a Faste Comprising a mixtureiof an active material, a binder, and ingrecheis capabie of chemical reaction to produee a gas, drying the piateyand snbseij uentiy fol-min":- the piaia.

2. 'i he procem of producing 2.. atom battery positive plate which comprises ing a smaobio gf-ui with a paste comprising; a mixture of an active materiai; u bindei', on acid, and a carbonate, dryin the pieie, and subsequently formi the pits.

The process of producing a storage batter positive piate which comprises fiiiproniucing :1 storage" inga suitable grid with a paste comprising an active material. collodion, glycerine, sulfurioacid, and a sodium carbonate, drying the plate, and subsequently forming the plate.

6. The process of. producing a. storage batter positive plate which comprises tilling suitable grid with a paste, comprising a mixture of an active material, collodion, g lycerine, sulfuric acid, and a sodium coronute, drying the plate, and subsequently forming the plate in -a solution comprising water, =1 sodium carbonate, and aluminum sulfate.

'8. A filling paste for a storage battery positive grid comprising a mixture of an active material, a binder, and ingredients capable of chemical reaction to em ve a gas.

9. A filling paste for a. storage battery positive grid comprising :1 mixture 01 an active material, a binder, an acid, and a carbonatc.

10. A filling paste for a. storage battery positive grid comprising u nnxtureof an active material, a binder, sulfuric acid, and

a. sodium carbonate.

12. A filling paste for a storage battery positive grid comprising. smixture of an active mcterichcollodion, sulfuric acid, and a carbonate.

13. A filling paste for a storage battery positive grid comprising a, mixture of an gruvityone pint, collodion one ounce, sodium bicarbonate one-half ounce, and glycerine one ounce.

16. A filling paste for a storage battery positive ricl comprising a mixture of sulfuric acid of approximately twelve hundred degrees specific gravit one pint, collodion one ounce, sodium icurbonate one-half ounce, glycerine one ounce, and red lead,. as an active material, in quantity suflicient to form a paste.

17. A storage buttery positive plate having a filling which has been rendered porous by the evolution of a. gas therein.

18. A stornge'battery osltive lute comprising an active inateria and u inder and which filling has been rendered porous by the evolution of a gas therein.

19. A storage battery positive plate hovlll u filling comprising an active material. collodion, and glycerine, end which filling has been rendered porous by the evolution of a gas therein.

20. The process of producing a storage battery positive plate which includes the step of generating a gas in the filling paste for the plate whereby to render the said filling porous and permeable.
